摘要
开展了降低海绵钛致密度的优化试验,研究了加料速度、反应温度、液面高度以及加料方式对海绵钛致密度的影响。结果表明:采用多点布料和降低料速,海绵钛产品的平均装桶率可达到63.0%和62.6%;还原温度降低100℃和还原液面降低150 mm条件下,装桶率可达到61.3%和61.2%。试验所得产品符合国标中0级品的标准。SEM图像表明试验产品仍保持了原有的层状海绵结构。
The optimal experiments for reducing compactness of titanium sponge were carried out,and the influences of feeding speed,reaction temperature,liquid height and feeding way on the compactness of titanium sponge were studied. The results show that the average barrel rate of titanium sponge can reach to 63. 0% and 62. 6% by multi-point feeding and reducing the feeding speed,respectively. By reducing the reduction temperature and liquid height by 100 ℃ and 150 mm,the average barrel rate of titanium sponge can reach to 61. 3% and 61. 2%,respectively. The obtained titanium sponge in the experiments meets the 0 grade of the national standard. It can be seen from SEM images that the products in the experiments have the original layered sponge structure.
